16. A Couple with the ability to taste PTC have two grown sons and one grown daughter. The sons have the ability to taste PTC. Their daughter is a PTC non-taster. She married with a PTC non-taster man and have two sons.
The ability to taste Phenylthiocarbamide<span> or PTC is inherited by autosomal dominant trait. The daughter of the first generation should be autosomal recessive(tt) as she was a non-taster. That means her parent would be heterozygotes(Tt) since they have the ability to taste PTC. Her brother could be homozygote dominant(TT) or heterozygote(Tt). The pedigree would be:
i. no-shade square(Tt) -----------------</span>no-shade circle(<span>Tt)
ii. </span>no-shade square(T?), no-shade square(T?), shaded circle(tt)------shaded square(tt)
iii. shaded square(tt) and shade square(tt),
17. She marries with non-taster too which means also a homozygote recessive. Since both parents are homozygote recessive, the children should be 100% homozygote recessive too.
The phenotype of the sons in generation III would be 100% non-taster.
18. The genotype of the female should be XX. To express the recessive trait, an individual need to have all recessive genes. If she has a recessive trait of an X-linked disease then both of the X genes should have a lowercase letter(recessive).
Answer:
C.


19. The genotype of a male should be XY. If he has a recessive trait of an X-linked disease then the X genes should have a lowercase letter(recessive). As there is only one X gene in male, to express recessive he only needs 1 recessive gene.
Answer:
E.

Y
If I notice that invoice and Yolanda are regularly collected and that I fill in my inference that they're now enthusiasts, then I am illustrating the perception concept known as closure.
Perception is a highbrow process of remodeling sensory stimuli into meaningful information. it is the system of decoding something that we see or pay attention to in our mind and use later to judge and deliver a verdict on a situation, character, organization, and so forth.
The perception now not simplest creates our revel in of the world around us; it lets in us to behave inside our surroundings. perception is very vital in knowledge of human behavior because anybody perceives the sector and processes life troubles in a different way.
For instance, upon walking into a kitchen and smelling the scent of baking cinnamon rolls, the feeling is the scent receptors detecting the smell of cinnamon, however, the belief may be “Mmm, this smells like the bread Grandma used to bake while the circle of relatives amassed for holidays.”

<u>Cost center responsibility</u> reports typically focus on the flexible budget variance, which is the difference between actual results and the flexible budget.
<u>Explanation</u>:
The cost center is the responsible center where the manager is only responsible for controlling costs. It is his duty to track the expenses. The performance evaluation of the cost center is based on its flexible budget variance.
The flexible budget variance generally provides the difference between actual results and the flexible budget. The cost center is of two types:
i) Production cost center
ii) Service cost center
The production department, maintenance department, accounting department and human resource department together form the cost center.
According to a research study, smoking and cholesterol interact to produce higher rates of heart disease than would be expected from their individual risks.
Minor Challenges: The excitement of riding a roller coaster, a scary movie, or a fun challenge are examples of eustress. Even a particularly hard workout can be an example of this type of stress. New Experiences: Traveling can also generate eustress.
